I think he has just been an easy target lately. I like Donaire and there are a lot of good things about him.
He probably will never be his super aggressive self or have the quickness he used to have. But, he definitely looked better than he did vs. Vic.
People forget he is the ONLY boxer (as far as I've heard) to do the year round VADA testing. 24/7, 365 (at Donaire's own expense) he can be tested to make sure he is substance free.
I'm not too hard on him either for yesterday. HBO's feed was pretty bad, so you couldn't tell the exact moment he got cut, but he definitely was butted 3 or 4 times in the fight, including around when the cut appeared. As fans we def love fighters who are warriors and fight through, but if it was a butt, Donaire was at a huge disadvantage for the rest of the fight - it was a really bad one - so I don't blame him for wanting to win/lose at his best.
Plus, I agreed with the judges - I had Donaire up 3-1, plus an extra point for the KD. Vetyeka really wasn't doing anything, except landing a few quick shots here and there. Fight seemed to be going Donaire's way and the only thing that appeared to hurt his chances was that eye.
edit: And I liked his post fight interview as well. He didn't want any credit for the fight or the KD. He said he owed Vetyeka a rematch so it could be decided by the fighters themselves.
